naledin bearings 14: provided in upwardlyextending brackets 15 locatetl' near the front ends of the frame members l, and the lower end or portion 13 of the front cranli rnem ber 10, is iournaled or pivoted in bearing, .16 provided on the beam 9. The lower end. of the crank member 10 moves upwardly and rearwardly in an arc of approximately Be it known that I, 'WILIJAM H. Lee, of Syracuse in the county of. Onondaga and State of ew York, have invented a certain new and useful Means for Raising and Lowering the Earth-Turning Elements of Wheeled Plows, of which the following is a specification.

My invention relates to wheeled plows, and has for its object a particularly simple and efficient means for raising and lowering the earth-turning elements thereof; and it consists in the combinations and construetions hereinafter set forth and claimed.

In describing" this invent-ion reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are side elevations of a dotted line 17 during the raising the earth-turning element and the crank lurinber 10 thus moves from a nearly vertical position to a nearly horizontal position.

The pivots or spindles 12 of the rear 18 provided at the ends of brackets depending from the rear ends of thefranie wardly and upwardly out of and above the horizontal plane passing through the of its lower end, and the portion 13 w 1' "front end is journaled in a bearing 29 provided at the upper'end of a bracket 23*. asso ciated with the beam. 9 of the earth-turning element. During the raising of plow, the front end of the member 11 moves upwardly and rearwardly in an arc consider-- ably less than a quarter of a circle as indi' cated by the dotted line 22. Thus the ends of the crank members 10 and 11'. are inovable in arcs extending between the axes of said members, and the axis of the front crank member 1.0 is arranged shove the horizontal plane of the axis of the rear nienr ber 11. By constructing and arranging; the members 10 and 11 as described, the end. of :lhe 'ilront member or bail 10 connected to the beani 9 moves rearwardlyduring the {initial movement of said bail, and the end of the rear member or bail ll connected to said beam moves upwardly during its initial movement, and consequently the rear end of the beam 9 is first raised faster than the front end of said beam, and. the front end of the beam is first lowered to the ground in advance of its rear end.'

As seen in Fig. 3, the crank members or plow being omitted, and the earth-turning in their positions occupied, respectively, when said element is lowered and raised. Fig. 3 is a plan oi parts seen in Fig. 1,. parts The frame of the plow may be of any desirable form size and construction, and is here shown as comprising opposite longitudinal frame bars 1 having croes bars 2 at their ends.

3 is a rear furrow wheel mounted on an axle 4-. carried at'the lower end of an upwardly-extending spindle 5 which is journaled in the upright bearing 6 formed in a bracket 7 secured tothe rear cross bar 2 of the frame.

8 is the earth-turning element or plow proper which is carried by theusual beam 9.

l0 and 11 are front and rear crank 1neinhere by means of which the earth-turning element is supported and guided when being raised and lowered the front member 10 becrank members 10 and 11 are usually in the form of bails, the ends of which are extended laterally forming spindles 12 which are journaled'in bearings provided onthe frame. .The intermediate portions 13 of the bails are journaled in bearings provided on the beamof the earth-turning element.

The front crank member 10 extends downwardly nearly vertically from its axis and tudinal alinement so that the beam 9 is arranged at an obli ue angle-to the frame or line of travel of t e plow.

The movement of the earth-tn ment is controlled by a lever 1 a reel: shaft journaled in a bear av quarter of a circle as indicated the crank member 11 are journaled in. bearings members 1, and said member 11- entends for.

bails 10 and 11 are arranged out of lougi ting the earthturnin which is carried at the upper end of an upright bracket 26 supported by a frame bar 1 between the brackets 15 and 19, said shaft 24 having a rock arm 27 extended forwardly and downwardl therefrom, and pivoted at "28,110 one end 0 a link-29, which is pivoted at its other end at 30, to the beam 9, the

parts 27 and 29 forming a toggle. One of the parts, as the arm 27, is here shown as p'i'ih'ided with means-for limiting the movement of said arts 27 and 29 and as here shown, the rec arm 27 is provided with a bracket 31 extendin beyond the pivot 28,

and carryingzan ai ustable shoulder as a 10 screw 32 extending rough the bracket and engaging an edge of the link 29. Obviously,

b turning the screw, the extent of movement of the pivot 28, beyond a straight line pass ing through the axes 24' and 30, can be ad- 'usted, B depressing the lever 23, the

cam 9 an the earth-turning element 8 will be raised, and will be guided in their upward. movement by the crank members 10 and 11.

2.3 The earth-turning element'is held in its raised position by means of a catch or look 33 pivoted intermediate of its ends at 34 to the rock arm 27, and provided with a hookshaped engaging part 35"at the end of/one .30 arm, this part 35 movinginto and'o t of engagement with a fixed shoulder 36 provided on the bearing 25. *Astli lever 23 is depressed and the arm"?! r ised, the

catch 33 is raised therewit wentil its end 35 Top latches over the fixed shoulder 36. Said catch is usually formed with a slot 37 which receives the pivot 28 of the toggle. The catch may be moved out of operative posi- "ltion by depressing the other arm 38 thereof -j'4 0 and thus moving'the hook 35 out of en- I gagementwith the shoulder 36, and permitelement 8 to be [moved by its own weig t to the ground.

- The raising of the earth-turning element 5.6 8 is facilitated by a horizontally-extending spring 39 connected at its rear end at 40 to a bracket 41 provided on one of the frame bars 1, and at its front end to a link 42, which is pivoted at its front end to a rock *arm', provided on and rigid with the Sign 12 of the front crank member 10, said 1 arm 43 being arranged at an angle to the 1 front member 10 in'order that the leverage of the arm 43 will increase as theplow 8 is I raised and the spring 39 grows weaker, and i the member 10 moves upwardly. ,In raisl ing the earth-turning element 8, the depression of the lever 23 suffioiently to move the pivot 28 of the toggle to the front side of the straight line passing through the axes I 24, 30, moves the arm 43into a position -in which the spring can act most efficiently upon the crank member 10.

WhatI claim is In a wheeled plow, a fume, an earth turning elementhaving a beam, means for raising and lowering the earth turning element comprisin front and rear bails, the front bail extending downwardly and being pivoted at its upper end to the frame, and at its lower end to the beam, the rear bail extending upwardly and forwardly and being pivoted at its rear end to the frame and at its frontend to the beam, the front bail being horter than the rear bail and moving '75 during the raising of the beam from a nearly vertical depending position to a nearly horizontal position through approximately a quarter of a' circle,,and the longer or rear bail being inclined out of and above the horizontal plane passing through its axis and moving through an are considerably less than a quarter of a circle, whereby d uring the movements of the bails, the pivotal connections thereof with the beam move in 8,5 difi'erentdirections, that of the front bail movingl rearwardly during the initial movement t ereof and that of the rear bail moving 11 wardly so that the rear end of the and the front end is first lowered to the ground in advance of the rear end, substantially as and for the purpose described.

In testimony whereof, I have hereunto signed my name in the presence of two at- 95 testing witnesses, at Syracuse, in the county of Onondaga in the State of New York, this 22nd day of ept, 1910.
